This invention relates to machines for preparing and securing strips such as Welts or rands to the .margins of shoe parts having curved edges and-is herein shown, by Way of illustration, as embodied in a ma chine organized for slashing and securing rands or the like to heels or heel lifts.v Among the objects of the present invention are to enable the strip to be more firmly se cured, to reduce the number of fastenings necessaryto secure a given length of strip, and to enable short lengthsof strips suc-lras taper section rands to ,be inserted in the machine with greater facility.

With these object m e feature of the ventionconsists ofjthe combination, in

an or anization comprising mechanism for handling, feeding and insertingloose, head ed fastenings such as tacks, of strip guiding means, and slashing mechanism operatedto out successive slashes in the strip as the in s ertion of the fastenings progresses. As illustrated herein, the organization includes Work-feeding mechanism comprising a ro tating Work table and feed Wheel between which the Workand strip are clamped and by movement of which they are fed,'and

slashing means operated to cut progressively through theinai'gin of the strip from one edge of the strip toward the other edge and preferably at an oblique angle to the plane of the strip. Mechanism is provided for in-.

creasing the work sustaining pressure in conjunction With the setting of the fastening inserting mechanism into operation, for 8X-' ample by operation of ,a treadle, and preferably the same treadle is utilized to con-- trcll'the operation of the slashing means, for example, by further movement thereof after the fastening inserting mechanism is in operation.

Another feature of the inventionconsists in an organization including fastening in-l' serting mechanism for securing a strip of material along the margin of a piece-of stock having a curv'ed'edge, with slashing mechanism operating to make successive slashes in the strip,.t0 facilitate bending of the strip,

at a frequency different from the'operations of the fastening inserting mechanism. As iilustrated herein, a plurality of slashes, for example two, are made in the strip for each fastening inserted.

way of example, is similar Another feature of the invention consists, 111 a novel construction of a strip or rand guide-comprising astationary and a movable "portion one of 'Wl11Cl1 is formed to provide' a guard for the slashing knife and the] bers Will be separated when the. machine stops to facilitate the insertion of a. new

strip or rand and to insure that the guide*- Will be closed to guide the'rand before the machine is started.

The above and otherfeatures of the invention Willbecome more fully evident to 5 those skilled inthe art from the followingv description of a preferred form of the in:- vention and from the appended claims.

'1','1()6,393, granted August 11, 1914, on application of Fred L. Mackenzie. Inmach-ines .of this type headed tacks are placed in bulk; in ahopper 1 from Which they are fed'to a} .nozzle 2 to be driven intothework by a vertically reciprocating driver. According to the present invention, there is secured on. the left-hand side of the head of the Ina-f chine '(Fig. 2) a casing 8 in Whichare bear ings for a driving shaft 4; parallel to a main f 7 ice shaft 6 of the ltacker mechanism, the driving shaft 4 having rotatably mounted upon it a driving pulley '8 Which is driven 'froma suit-1 able source of power. "The pulley 8 may be coupled to the driving shaft 4 by a clutch of any suitable type, preferably one whlch will cause continued operation of the machine while the treadle is held depressed and Will stop the machine ata predetermined point in the cycle when the treadle' is re leased. The main shaft (3 of the machine is driven from the driving shaft 4 through suitable gearing 12 2) at half the speed of the driving shaft 4, and the main shaft 6 has fixed on itan eccentric 14 whicluthrough a connecting rod 16, controls a clutch tripand lever 18 comprises a rod 19.

A; slashing knife 20 is located on the right-hand side of the, machine and is fixed onanlarm22 secured to the upper end of a verticalisliaft 2d mounted to rotate in bearings 25,26 formed. on the head of the machine. ,The shaft 24 is adjustable vertically by means of a screw 28 threaded through a lug 30 projecting from the head and located beneath the lower end of the shaft 24 which is held in engagement with the screw 28 by a spring 32 surrounding the shaft and confined between thelower face of the upper bearing25 and a pin 34 extending through the. shaft 24. The knife carrying arm 22 is connected a horizontal link 36 to the lower end of the lower portionfifl of a two part arm 38, 42 pivotally mounted on a shaft 4O parallelto, and below the driving shaft 4.

As shown in Fig. l, the joints between link 36 and the'knifc carrying arm and hes tween link 36 and the lower portion 38 of arm 38, 4-2 are ball and slot joints so that link 36 may have the necessary transverse play. The two parts of arm 38, 12 are pivoted together by a pin 46 located beneath. and transversely of the shaft -l-(l so that the arm as a whole can swing about the :naft and the lower portion 38 of the arm can swing lengthwise of the shaft The lower portion 38 of the arm 15 held toward the frontof the machine by suitable spring 48 and, when the machine is at rest such 'movement is prevented by engagement of the lower'end of said arm with a vertically dis oosed late 50 carried 1) the clutch triol L o u L plug lever 18, but when the clutch tripping lever is fully depressed the plate 50 is moved outof engagement with the lower portion 38 of the arm and this portion is swung, by its spring 48,1engthwise of the shaft' ltl into engagement with a groove formed in the block 52 adjustably secured at 5% to the lower arm 56 of a cam lever pivotallv mounted on a 'sleeve 58 extending from'the toward the stationary rand gnidet-S c the machine is depressed,

by a spring part 42 of the two-part arm 38, 42 through which the shaft 40 passes' The upper arm 60 of the, cam lever carries a roll 62 which enters a cam groove 6st formed in a cam 66 fixed on the driving shaft i. The cam groove 64 is so formed that when the lower portion 38 of the two-part arm 38, 4-2 is in engagement with the groove in the block 52 one cutting movement is imparted to the slashing knife 20 during each revolution of the driving shaft 4 and, as the main shaft 6 is driven at half the speed of the driving shaft, two cuts will be made between the driving of successive tacks. The upper edge of the plate 50 of the clutch tripping lever 18 and the loweredge of the portion 38 of the two-part arm 38, 42 are suitably-beveled so that when the clutch tripping arm 18 rises to release the clutch the lower portion 38 of the twopart arm 38, 4-2 is disengaged from the groove in the block 52 on the cam lever 56, 60.

The strip or rand isguided to the tacking mechanism by a stationary block'68 having a face 70 downwardlyl inclined from the right and upwardly inclined'toward the rear of the machine (Fig. 3). A vertical face atthe rear of the inclined face 70 acts as a rand edge guard. The rand passes below the inclined face 70 andthen below a horizontal face 72'uponthe block 68 into which The slashing 7 cal shaft 2% under the horizontal face '72 and cuts progressively through the rand for a part of its width from the edge nearest the operator towardits other'ed 'e, the knife effecting a shearing out in co-operation with the edgeformed by the junction of the inclined andh'orizontal faces 7 O and 72 of the rand guide. The knife first enters the rand at the junction, of that rand edge face nearest the operator and the bottom face of the rand and a slash is directed in the ra'ne so to extend forwardly and upwardly there in in the direction of feed (see Fig. 3).
